Abstract
A method for identifying an occurrence of a concussion in a subject involves capturing eye blink raw data from at least one eye of the subject. The method next involves analyzing the eye blink raw data to generate at least a first subject specific eye blink metric and determining that a significant difference exists between the first subject specific eye blink metric and a predefined normal value. Next, the occurrence of the concussion in the subject may be identified, based on determining that the significant difference exists.
Claims20
A method for identifying an occurrence of a concussion in a subject, the method comprising:
- seating the subject in front of a display at a distance of between 10 and 90 cm, and presenting a visual stimulus on the display;
- capturing eye blink raw data from two eyes of the subject in response to the visual stimulus using an eye tracking device having a camera at a frequency greater than 500 Hz to obtain a sample over at least 30 seconds;
- analyzing, via a processor, a measure of how often blinks from the two eyes overlap over a period of time when subjected to a common visual stimulus on the display;
- and
- identifying, via the processor, the occurrence of a concussion in the subject based on the measure.

- counting a number of blinks in a first eye of the subject that do not have a corresponding blink in a second eye of the subject;
- and
- identifying, via a processor, the occurrence of a concussion in the subject based on the counted number of blinks.
